Steel dam gate device with anti-slipping-down function

Abstract

The invention discloses a steel dam gate device with an anti-slipping-down function in the technical field of steel dam gates. The steel dam gate device comprises a center rotating shaft, a gate plateand a pair of control rooms and further comprises a PLC and a hydraulic system controlled by the PLC. The control rooms are internally provided with indoor foundations. Each control room is internally provided with a swinging oil cylinder, a main hinge seat, a rocker arm, a locking cylinder and a lock pin. The rocker arms are fixed to the peripheral surface of the center rotating shaft. The tailend of a piston rod of each swinging oil cylinder is hinged to the corresponding rocker arm. A double-lug locking seat is mounted on each indoor foundation. Each double-lug locking seat is provided with a free gap capable of allowing a swinging plate to be inserted in. A main locking hole is formed in each swinging plate. A locking seat hole is formed in each double-lug locking seat. When the gateplate is located at an erecting and water blocking state, the main locking holes in the swinging plates exactly correspond to the locking seat holes of the double-lug locking seats and the main locking holes and the locking seat holes are coaxial, the swinging plates are exactly located in the free gaps, the lock pins directly face the main locking holes and the locking seat holes and are inserted in the main locking holes and the locking seat holes, and the rocker arms can be located at the accurate locking positions accordingly, so that the oil cylinders are locked to lock the rocker arms.

Description

technical field [0001] The invention relates to the technical field of steel dam gates, in particular to a steel dam gate device with an anti-sliding function. Background technique [0002] At present, the steel dam gate already has a very good anti-sliding function. Its structure includes a horizontal central rotating shaft, a gate plate installed on the central rotating shaft, and a pair of control rooms respectively arranged at both ends of the central rotating shaft. It includes a PLC controller set in the control room and a hydraulic system controlled by the PLC controller. The control room is equipped with an indoor foundation, and the end of the central shaft rotatably passes through the control room and is rotatably mounted on the indoor foundation. Each The control room is equipped with a swing oil cylinder, a main hinge seat, a rocker arm, and a locking oil cylinder. The control room is also equipped with a lock pin coaxially spliced ​​with the piston rod of the lo...

AI Technical Summary

Problems solved by technology

[0004] However, when the swing cylinder drives the rocker arm, the central shaft, and the gate plate to rotate, the rocker arm often cannot be accurately changed to an accurate locking position, so that the lock cylinder cannot lock the rocker arm smoothly.
